My assumption, the materials. "Hand-carved copper housing, crystal and silver-plated copper cable, Leather carrying case" sounds pretty off the walls expensive to me.
I own the OH7. In my opinion they sound absolutely amazing. They somehow make music more
enjoyable. That is what makes them great in my opinion. It is difficult to describe how they do it
Bass is very, very good, mids are not too special in my opinion and the highs are pleasantly soft. It is definitely not an analytical IEM. It sounds very different to triple BA IEM's like for example the Shure Aeonic 5. Maybe a bit less resolution, but man do i enjoy these! I highly recommend them to people who are not looking for an analytical IEM but are looking for an enjoyable sound. When i first listened to them they immediately hit me as something special. Other details: the cable is very soft (softer than it looks) and does not tangle. Fingerprints can show a bit on the back of the IEM but are easily removed with a cloth and they have a bit of weight to them. I hope my answer helps a bit.
In return/replace policy it says "Drop Studio items are considered eligible for return if they [...] are marked on the product page via a note stating 'RETURNS & EXCHANGES—NO QUESTIONS ASKED'". I cannot find this sign anywhere on this page so I'm assuming that I couldn't return the Ikko OH 7 if I where to purchased them and didn't like them.
Am I correct with this one or
